We can expand this expression using foil method (multiply first terms, outer terms, inner terms then last terms together):
<span>(x+4)(x+6)
x^2 + 6x + 4x + 24
combine like terms
x^2 + 10x + 24
This is also the final simplified expression. It cannot be further expanded or simplified. Foil method is the easiest way to expand expressions.</span>
How long will it take them to clean the bedroom? 10 minutes

ANSWER: √(5263.14) = 72.547502
Multiply both sides by -1
|-x|=12
-x=12
x=-12
-x=-12
x=12
Final answer: D
Answer:
w⁴ - 36
=> ( w² )² - ( 6 )²
=> ( w² + 6 ) ( w² - 6 )
=> w² + 6 = 0 and w² - 6 = 0
=> w = √-6 and w = √6
